respond

respond: [16] Respond comes from Latin respondēre ‘promise in return’, a compound verb formed from the prefix re- ‘back’ and spondēre ‘promise’ (source of English sponsor, spouse, etc). The notion of ‘obligation’ survives in the derivative responsible [16]. The Italian descendant of respondēre is rispondere, whose feminine past participle risposta has given English riposte [18] (originally a fencing term).
=> sponsor, spouse

respond (v.)

c. 1300, respound, from Old French respondere "respond, correspond," from Latin respondere "respond, answer to, promise in return," from re- "back" (see re-) + spondere "to pledge" (see spondee). Modern spelling and pronunciation is from c. 1600. Related: Responded; responding.
